“Once he got injured there was no timeframe but it gives others a chance. It gives opportunities to other people. People have come in and done well. It didn’t seem there were any other problems,” he added.

Atletico Madrid

Atletico have several squad members also unavailable. Tiago, Augusto Fernandez, Miguel Ángel Moya and Sime Vrsaljko will all miss the first leg, with Kevin Gameiro and Nicolas Gaitan rated as doubtful.

What have they been saying?

Craig Shakespeare has conceded his team face an uphill challenge to qualify for the semi-finals of the Champions League.

“Facing a team who have reached the final in two of the last three seasons is a massive challenge but it’s just the kind of tie you expect in the quarter-finals of the Champions League,” admitted Shakespeare.

“Atletico Madrid are a very good team with some fantastic individuals with experience in the competition, but we’ll be ready to give everything to progress.

“It will be a brilliant occasion for our supporters and for everyone at the club.”

However Emile Heskey has backed his former side to spring another shock less than a month after knocking out Atletico Madrid's La Liga rivals, Sevilla.

“I think the first leg will be a tight and cagey affair away from home.

“But I definitely think Leicester have a good chance of scoring [with] the likes of Mahrez, Vardy, Gray, Albrighton. I think they’ve got more than enough firepower to get at least one goal against Atletico Madrid.

“I’m going for a 1-1 draw in the first leg, then Leicester can bring Atletico back to the King Power and put on a good display in front of a home crowd.

Manchester United target Antoine Griezmann has warned his Atletico Madrid teammates not to under estimate the Premier League champions.

“We know how strong Leicester are. They are a bit like us in the way they play. They have a similar spirit to us and they are going to be difficult opponents, for sure,” said Griezmann

“Hopefully we will be in good shape against Leicester because this game is so important,” he added.
